WebThe C library function char *ctime (const time_t *timer) returns a string representing the localtime based on the argument timer. The returned string has the following format: … Websrand () is used to seed the random number generator (and only needs to be called once, best to do this at the start of main ()). The seed value could be obtained from user input, but usually the best way is to use the time value obtained from the computer's clock, since that will change frequently (like between runs of the program)

WebTo get a different series of random numbers each time the program is run, the time that the program is run can be passed as the seed value for the random number generator. This is done as follows: srand (time (0)); If the time function is used, make sure to include the ctime library as well.
